    Nyckelord :HUMANIORA; HUMANITIES; Pierre Schaeffer; Knut Wiggen; Groupe de Recherches Musicales; Elektronmusikstudion; Lasse Thoresen; Aural Sonology; electroacoustic music; acousmatic music; music concrète; text-sound; tripartition; poietic level; neutral level; typo-morphology; Gestalt; Pierre Schaeffer; Knut Wiggen; Groupe de Recherches Musicales; Elektronmusikstudion; Lasse Thoresen; Aural Sonology; musique électroacoustique; musique acousmatique; musique concrète; tripartition; text-sound; niveau poïétique; niveau neutre; typo-morphologie; Gestalt; Musicology; musikvetenskap;

    Sammanfattning : La thèse en question trace un parcours comparatif sur les approches créatrices et technologiques qui ont été développées au GRM (Groupe de Recherches Musicales) et à l’EMS (Elektronmusikstudion) de 1965 à 1980. Cette recherche vise à étudier les interactions principales entre les concepts musicaux des pionniers des musiques électroacoustiques en France et en Suède, Pierre Schaeffer et Knut Wiggen et l’évolution des directions artistiques au sein de leur institutions.

  3. 2. Grid Connected Three-Level Converters : Studies for Wave Energy Conversion

    Författare :Remya Krishna; Mats Leijon; Karin Thorburn; Uppsala universitet; []
    Nyckelord :Wave energy; power converters; control strategies; grid connection; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : This thesis presents an electrical system analysis of a wave energy converter (WEC) for the objective of grid connection. To transfer the enormous amount of power from waves to the load centers, efficient power electronic systems are essential. LÄS MER

  4. 3. Multilevel Power Converters with Smart Control for Wave Energy Conversion

    Författare :Deepak Elamalayil Soman; Mats Leijon; Jan Isberg; Sebastain Nielebock; Gopal Mondal; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multilevel power converter; FPGA control; Wave Energy; Three-level boost converter; Three-level buck-boost converter; Variable-renewable-energy; Three-level neutral point clamped inverter; Linear generator; DC-link; AC2AC direct converter; Modular multilevel converter; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : The main focus of this thesis is on the power electronic converter system challenges associated with the grid integration of variable-renewable-energy (VRE) sources like wave, marine current, tidal, wind, solar etc. Wave energy conversion with grid integration is used as the key reference, considering its high energy potential to support the future clean energy requirements and due the availability of a test facility at Uppsala University.

  5. 4. Mesoscale dynamics and boundary-layer structure in topographically forced low-level jets

    Författare :Stefan Söderberg; Michael Tjernström; Branko Grisogono; Douw G. Steyn; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; low-level jets; boundary layer; turbulence structure; Meteorology; Meteorologi;

    Sammanfattning : Two types of mesoscale wind-speed jet and their effects on boundary-layer structure were studied. The first is a coastal jet off the northern California coast, and the second is a katabatic jet over Vatnajökull, Iceland. LÄS MER

  7. 5. Neutrality in Internal Armed Conflicts : Experiences at the Grassroots Level in Colombia

    Författare :Pedro Enrique Valenzuela Grueso; Peter Wallensteen; Christopher Mitchell; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; neutrality; internal armed conflict; peace communities; Colombia; Peace and conflict research; Freds- och konfliktforskning; Peace and Conflict Research; Freds- och konfliktforskning;

    Sammanfattning : Civilians in situations of armed conflict are not exclusively victims or fence-sitters, but engage in a wide array of strategies along the spectrum from passivity to activity. Nevertheless, the privileged focus on eliteled processes has neglected peacebuilding efforts at the grassroots level, despite their increased saliency in internal armed conflicts and their potential impact on their regulation and/or transformation.
